Safety Information
Most accidents with walk-behind mowers can be prevented if
you follow all instructions in this manual and on the mower.
The most common hazards, according to accident statistics,
are discussed below, along with the best way to protect
yourself and others.
Avoid Rotating Blades
A rotating blade can cause serious cuts and even amputate
fingers, hands, toes, or feet. Keep away from the mower
deck whenever the engine is running. If you need to work
around the deck to clear a grass accumulation, adjust the
cutting height, or for any other reason, always shut off the
engine and remove the key. Wear heavy gloves when you
need to clean the mower deck or handle a blade.
Clear Mowing Area
Mower blades can throw rocks and other objects with
enough force to cause serious injury. Before mowing,
carefully inspect the area and remove all sticks, stones,
pieces of wire, and other loose objects. Never operate the
blades over gravel.
Keep Shields in Place
Guards and shields are designed to protect you from being
hit by thrown objects and from touching hot engine parts and
moving components. For your safety and the safety of
others, keep all shields in place when the engine is running.
Refuel with Care
Gasoline is extremely flammable and gasoline vapor can
explode. Refuel only outdoors in a well-ventilated area with
the engine OFF. Never smoke near gasoline, and keep other
flames and sparks away. Always store gasoline in an
approved container.
2
MOWER SAFETY
Wear Protective Clothing
Wearing protective clothing will reduce your risk of injury.
Long pants and eye protection reduce the risk of injuries from
thrown objects. Sturdy shoes with aggressive soles will help
protect your feet and give you better traction on slopes or
uneven ground. Ear protection and a helmet may be required
by local ordinances or insurance policies.
Turn Engine Off When Not Mowing
If you need to leave the mower for any reason, even just to
inspect the lawn ahead, always turn the engine off. And take
the key if you go farther away.
Important
Message to Employers
As an employer, you have special responsibilities
people who work for you.
to the
Before you ask anyone to operate this mower, you need to
determine whether the person is old enough, large enough,
and strong enough to safely handle and control the mower.
If you decide they are, make sure the employee reads and
understands all instructions and warnings in this manual and
on the labels before operating the mower.
Allow adequate time for hands-on training by a qualified
instructor, and personally supervise practice sessions until
you feel sure the employee is ready to operate the machine.
Also be sure employees wear proper clothing and have eye
protection and any other gear that may be required by local
ordinances or your insurance company.
Remember, too, that you are responsible for keeping the
mower properly maintained and in safe operating condition.
Your commitment to safety on the job can help prevent
accidents and result in longer and more productive years of
service.

+k
There is one very important thing to
remember when transporting your
mower: when you open the pump
bypass valves to move the mower
without the running engine, you
disable all braking action. For this
reason:
l
l
l
l
Always close both pump bypass valves after moving the
mower by hand.
Always drive the mower under its own power on any
incline.
If you must move the mower on an incline without
running the engine, use a suitable device (winch, block &
tackle, come-along). Remember that the mower weighs
over 272 kg (600 lb).
When moving the mower without running the engine, do
not move it at more than a walking speed or more than
91 meters (100 yd). Be sure the bypass valves are open
at least one turn but not more than two turns.
See page 28 for more information on operating the bypass
valves.
Transporting
your Mower
Use a loading ramp to get the mower on and off the vehicle.
Be sure both the ramps and vehicle are able to support the
weight of the mower and operator.
When the mower is in position, turn the fuel valve OFF to
prevent the possibility of fuel leaking.
Tie the mower down, front and rear, with ropes or straps.
You may use the front caster brackets and the rear cross
member to tie the mower down. Be careful not to damage
hoses or linkages when tightening the ropes or straps.
Remember that the engine and exhaust system become hot
during operation. Avoid touching them.

TRANSPORTING and STORING
Storing your Mower
When leaving your mower unattended, always:
l
Turn the key off and remove it from the ignition switch.
l
Turn the fuel valve off.

l
If you opened the pump bypass valves, close both of
them.
If you’re leaving the mower on a slope - even a slight
one - block both drive wheels front and rear.
Storage Preparation
,
Proper storage preparation is essential for keeping your
mower trouble free and looking good. The following steps will
help to keep rust and corrosion
from impairing
your mower’s
function and appearance, and will make the engine easier to
start when you use the mower again.
Cleaning
Wash the mower, including the underside of the mower deck.
Engine
Wash the engine by hand, and be careful to prevent water
from entering the air cleaner.
piq
Using a garden hose or pressure washing equipment can
force water into the air cleaner. Water in the air cleaner will
soak the filters and can enter the carburetor or engine
cylinder, causing damage.
Water contacting a hot engine can cause damage. If the
engine has been running, allow it to cool for at least half an
hour before washing.
Mower Deck
If using a garden hose or pressure washing equipment to
clean the mower deck, be careful to avoid getting water into
controls
and cables,
or anywhere
near the engine
air cleaner
or muffler opening.

(NOTICEI
Spraying water on hot mower deck bearings can cause them
to be damaged from cooling too quickly.
Before washing the underside of the mower deck, be sure
the parking brake is set and the height adjustment lever is all
the way up.
Grass Bag (optional kit)
Remove the grass bag from the frame, and wash it with a
garden hose or pressure washing equipment. Allow the bag
to completely dry before storage.
After washing the mower, wipe dry all accessible surfaces
Start the engine outdoors, and let it run until it reaches
normal operating temperature to evaporate any water
remaining on the engine.
While the engine is running, hold the operator presence
levers and operate the PTO clutch lever to expel water from
the blade pulleys, spindles, and other mower deck items.
Allow the blades to spin for several minutes to ensure that no
water remains.
Stop the engine and allow it to cool.
After the mower is clean and dry, touch up any damaged
paint and coat other areas with a light film or oil. Lubricate
the throttle cable core with a silicone spray lubricant.
Fuel
Gasoline will oxidize and deteriorate in storage. Old gasoline
and it leaves gum deposits that clog
the fuel system. If the gasoline in your mower deteriorates
during storage, you may need to have the carburetor and
other fuel system components serviced or replaced.
will cause hard starting,
18
TRANSPORTING and STORING
The length of time that gasoline can be left in your fuel tank
and carburetor without causing functional problems will vary
with such factors as gasoline blend, your storage
temperatures, and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank
promotes fuel deterioration. Very warm storage temperatures
accelerate fuel deterioration. Fuel deterioration problems
may occur within a few months, or even less if the gasoline
was not fresh when you filled the fuel tank.
Fuel system damage or engine performance problems
resulting from neglected storage preparation are not covered
under warranty.
You can extend fuel storage life by adding a gasoline
stabilizer that is formulated for that purpose, or you can avoid
fuel deterioration problems by draining the fuel tank and
carburetor.
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh
gasoline. If only partially filled, air in the tank will promote fuel
deterioration during storage. If you keep a container of
gasoline for refueling, be sure that it contains only fresh
gasoline.
Add gasoline stabilizer following manufacturer’s
instructions.
After adding a gasoline stabilizer, run the engine outdoors for
10 minutes to be sure that treated gasoline has replaced the
untreated gasoline in the carburetor.

TRANSPORTING and STORING
Placing in Storage
If your mower will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline
vapor ignition. Select a well-ventilated storage area away
from any appliance that operates with a flame, such as a
furnace, water heater, or clothes dryer. Also avoid any area
with a spark-producing electric motor, or where power tools
are operated.
If possible, avoid storage areas with high humidity, because
that promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the
fuel valve in the OFF position to reduce the possibility of fuel
leakage.
Park the mower on a level surface. Tilting can cause fuel or
oil leakage.
With the engine and exhaust system cool, cover the mower
to keep out dust. A hot engine and exhaust system can ignite
or melt some materials. Do not use sheet plastic as a dust
cover. A nonporous cover will trap moisture around the
’
mower, promoting rust and corrosion.
Removal From Storage
Check your mower as described in the Before Mowing
chapter of this manual.
If the fuel was drained during storage preparation, fill the tank
with fresh gasoline. If you keep a container of gasoline for
refueling, be sure that it contains only fresh gasoline.
Gasoline oxidizes and deteriorates over time, causing hard
starting.
If the cylinder was coated with oil during storage preparation,
the engine may smoke briefly at startup. This is normal.

Check the Mower
For your safety and the service life of your equipment,
always inspect your mower before using it. Before beginning
your pre-operation check, be sure:
The mower is parked on a level surface.
l
The blade control lever is disengaged and the ground
speed control levers are in NEUTRAL.
l
The ignition switch is off and the key is removed.
l
Walk around the mower and check its general condition.
Look around and underneath it for signs of fluid leaks.
Remove any excessive dirt and debris, especially around
moving components. Look for signs of damage. Check nuts,
bolts, screws, and pins for tightness.
Never operate the mower with the safety interlock system
inoperative.
Do not attempt to bypass
or defeat the system.
Keep all shields and covers in place while operating the
mower. If you find any problems or defects, have them
repaired before mowing.
Blades
Before each use, check each mower blade for damage or
abnormal wear. See page 67 for details.
Belts
Check the blade, deck, and pump belts for wear and correc,t
tension. See page 70 for details.
Engine Oil
Check the level on the dipstick. Running the engine with a
low oil level will cause engine damage. See page 46 for
details.
Hydrostatic Oil
Check the oil level in the reservoir. See page 54 for details.
Fuel
Remove the cap on the tank and check the fuel level. See
page 43 for refueling details.
24
BEFORE MOWING
Air Filter
Check that the air cleaner elements are clean and in good
condition. See page 42 for information on servicing the air
cleaner.
Cutting Height
The cutting height of your mower should be set for the
mowing conditions and should be in the same position, front
and rear. See page 63 to adjust cutting height.
Tire Pressure
Check the tires for proper inflation (page 62).
Check the Lawn
For your safety and the safety of others, always inspect the
area before mowing.
0 bjects
Anything which can be picked up by the blades and thrown is
a potential hazard to you and others. Look for things like
stones, sticks, bones, and wire, and remove them from the
mowing area.
People
People and animals near the mowing area can move into
your mowing path or into a position where they could be
struck by thrown objects. Clear the area of people, especially
children and pets. Their safety is your responsibility.
Lawn
Check the length and condition of the grass. Adjust your
mowing speed and cutting height accordingly.
Avoid mowing wet grass. Not only does mowing wet grass
result in poor cut quality, it also affords poor traction,
increasing your risk of losing your footing.

OPERATING
THE MOWER
-
The Honda Mid-Size Commercial Mower is a powerful, highly
maneuverable mower designed to enhance the productivity
of a lawn-care professional. You will need a complete
understanding of its operation and a certain amount of
practice with its controls to safely realize the full potential of
this mower.
Read this section completely before operating the mower.
Take time to familiarize yourself with the controls and how
they operate. Get used to the feel of the forward speed
controls and direction control levers by running the engine at
about half-throttle.
The small amount of time spent in familiarization
you with greater efficiency and reduced risk.
will reward
Starting the Engine
Because of the risk of carbon monoxide poisoning, it makes
good sense to start the mower outside; or at least in an open
area with good ventilation.
Pump Bypass Valves
In order to move the mower
from its storage area to a safe
place to start it, you must open
the pump bypass valves on
each pump. Open each valve
by turning it one turn counter
clockwise. When you’ve moved
the mower to its desired
position, close each valve by
turning it clockwise.
To avoid damaging the valves and their seals, do not open
the valves more than two turns and do not over tighten the
valves when closing them.
When the bypass valves are open, the normal braking action
of the hydraulic system is bypassed. Never move the mower
on slopes when the bypass valves are open. Always close
both bypass valves when you are finished moving the mower.
The mower will not move under its own power unless both
bypass valves are closed.
28
OPERATING THE MOWER
1. Pull the blade control lever to OFF. (The mower should not
be started without the entire grass catcher, the mulching
plug, or the guard in place.)
2. Pull both forward speed control levers to NEUTRAL.
The safety interlock system will prevent the engine from
starting if the blade control is ON or if the forward speed
controls are not in neutral. (Do not attempt to disconnect or
modify the safety interlock system.)
3. Squeeze both direction control levers to their neutral position
and apply the neutral locks by pulling them back with your
thumbs.
4. Be sure both pump bypass valves are closed.
5. Open the fuel valve.
6. Turn the key ON.
7. To start a cold engine, move the throttle lever to the CHOKE
position.
To restart a warm engine, move the throttle lever to the
FAST position.
8. When the engine warms up, move the throttle lever back to
the FAST position for mowing, or the SLOW position to idle.
For best engine performance, move the throttle lever out of
CHOKE position as soon as the engine will run smoothly.
Using the Direction Controls
The direction control levers allow you to control the speed
and direction of the mower.
OPERATING THE MOWER
The mower will quickly respond to the position of the levers.
To avoid abrupt changes of direction, squeeze the levers
slowly rather than treating them like a switch. Operate the
mower with the forward speed control levers in their SLOW
position until you are completely familiar with the sensitivity of
the direction control levers.
The direction control levers are spring-loaded to their
forward, or engaged, position. In this position the maximum
speed of the mower is controlled by the forward speed
control levers.
Moving Forward
1. Hold down one operator presence lever.
The safety interlock system will shut off the engine if you
move the forward speed controls out of neutral unless one of
the operator presence levers is held against the hand grip.
2. Move both forward speed control levers to the desired speed.
3. Slightly squeeze both
direction control levers just
enough to release the
neutral locks by pushing
them forward with your
thumbs. If you squeeze the
direction control levers too
far, you will engage
reverse. Squeeze them just
far enough to release the
neutral locks.
4. Slowly release pressure evenly on both direction control
levers and the mower will move forward.
Steering the Mower
To steer the mower to the right, gradually squeeze the
right-hand direction control lever. To steer the mower to the
left, gradually squeeze the left-hand direction control lever.
The more you squeeze a direction control lever, the slower
that wheel will turn and the sharper the turn will be.
30
OPERATING
THE MOWER
Zero-radius turns (turns in which the mower has no forward
or reverse motion - it just turns in place) are accomplished
by squeezing one direction control lever into reverse while
the other is in forward. Practice this maneuver at slow
speeds until you become accustomed to the mower’s
responsiveness.
Stopping the Mower
To slow the mower, slowly squeeze both levers the same
amount; the more you squeeze, the slower the mower will
travel.
When you squeeze to the neutral position, the mower will
stop. You may hold the mower stopped by engaging the
neutral locks, pulling them rearward with your thumbs.
Remember that if you release the operator presence levers
and the forward speed control levers are not in neutral, the
safety interlock system will shut off the engine.
Reversing the Mower
To reverse the direction of the mower, squeeze the direction
control levers toward the handgrips from the neutral position.
The more you squeeze, the faster the mower will travel in
reverse.
If the neutral locks are applied, when you release
direction control levers they will return to neutral.
neutral locks are not applied, releasing the levers

Making an Emergency Stop
To make an emergency stop, release the hand grips. When
you let go of the operator presence levers, the safety
interlock system will stop the engine and the mower will
come to a stop within 3 to 6 feet.
Starting to Mow
Al
!
A-
Objects hidden in the lawn can be thrown by the mower
blades.
Thrown objects can cause serious injury.
l Clear lawn of all debris before mowing.
l Do not operate the mower without either the
discharge chute, mulching plug, or the entire grass
catcher in place.
0 Wear eye protection.
l .Keep people and pets away.
For best cutting performance; always mow with the throttle
lever in FAST position. To begin mowing:
1. Be sure the direction controls are locked in neutral.
2. Hold down one operator presence lever.
3. Move both ground speed control levers to the desired
mowing speed. Always begin mowing with a slow ground
speed. Increase the ground speed to match mowing
conditions and your experience.
4. Slowly move the blade control lever to ON to start the blades
rotating.
5. Slightly squeeze both direction control levers and release the
neutral locks by pushing them forward with your thumbs.
6. Slowly release pressure on both direction control levers and
begin mowing.
Adjusting your Speed
Adjust the forward speed controls to set your best mowing
speed. If the mower does not travel in a straight path, you
may move one of the ground speed control levers ahead of
the other to make the mower track straight.
32
OPERATING
THE MOWER
If the mower’s path is drifting off to the right, move the right
lever slightly ahead of the let? lever. If the mower’s path is
drifting off to the left, move the left lever slightly ahead of the
right lever.
You may also use this method to control your path when
mowing on the side of a slope.
If the forward speed control knobs are separated by more
than one inch, the safety interlock system will shut off the
engine.
If the mower will not track in a straight path on level ground
within this range, the tracking must be adjusted following the
procedures on page 57.
Mowing Tips
Your mower is designed to trim closely on the left hand side
and discharge clippings evenly on the right hand side.
For best cut quality, run the engine with the throttle lever in
FAST.
Always mow in daylight, or under good artificial light.
Mowing on Slopes
There are two ways you can keep a straight path when
mowing across slopes:
l
l
Squeeze the direction control lever on the uphill side.
Adjust the ground speed control levers as described in
Adjusting your Speed (above).
Mow across slopes, not up and down. Avoid steep slopes
(more than 20’) and be careful when changing direction.
When changing direction, always turn the mower up-slope.
This will give you better control and help you maintain your
balance.
Avoid abrupt changes of direction or speed when operating
on slopes.
33
OPERATING
THE MOWER
‘-
Avoid stopping on a slope. If you must stop on a slope, block
the wheels securely if you leave the machine unattended. To
start on a slope, keep the throttle at SLOW to help you avoicl
abrupt changes of direction.
Mowing on a slope when the grass is damp or wet could
cause you to slip, fall, or lose control of the mower.
Parking the Mower

The Importance Of Maintenance
Good maintenance is essential for safe, economical, and
trouble-free operation. It will also help reduce air pollution.
To help you properly care for your mower, the following
pages include a maintenance schedule, routine inspection
procedures, and simple maintenance procedures using basiic
hand tools. Other service tasks that are more difficult, or
require special tools, are best handled by professionals and
are normally performed by a Honda technician or other
qualified mechanic.
The maintenance schedule applies to normal operating
conditions. If you operate the mower under unusual
conditions, consult a servicing dealer for recommendations
applicable to your individual needs and use.
Maintenance,
replacement, or repair of the emission
control devices and systems may be performed by any
enginerepair
establishment
or individual,
using parts
that are “certified” to EPA standards.
Incorrect maintenance, or failure to correct a problem
before operation, can cause a malfunction in which you can
be seriously hurt or killed.
Always follow the inspection and maintenance
recommendations and schedules in this owner’s manual.
Maintenance Safety
Some of the most important safety precautions follow.
However, we cannot warn you of every conceivable hazard
that can arise in performing maintenance. Only you can
decide whether or not you should perform a given task.
Failure to properly follow maintenance instructions and
precautions can cause you to be seriously hurt or killed.
Always follow the procedures and precautions

l
l
l
Make sure the engine is off before you begin any
maintenance or repairs. This will eliminate several
potential hazards:
-
Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you
operate the engine.
-
Burns from hot parts. Let the engine and exhaust
system cool before touching.
-
Injury from moving parts. Do not run the engine
unless instructed to do so.
Read the instructions before you begin, and make sure
you have the tools and skills required.
To reduce the possibility of fire or explosion, be careful
when working around gasoline. Use only a nonflammable
solvent, not gasoline, to clean parts. Keep cigarettes,
sparks, and flames away from all fuel-related parts.
For certain operations, the mower must be raised off the
ground. Be sure the mower is solidly supported before
you put any part of your body under the mower.
Wear heavy gloves when near the mower deck, belts, or
blades.
The mower uses pressurized oil to run the hydrostatic
drive system. Make sure all connections are tight and all
hoses and lines are in good condition before operating
the mower.
Remember that your authorized Honda servicing dealer
knows your mower best and is fully equipped to maintain and
repair it.
To ensure the best quality and reliability, use only new,
genuine Honda parts or their equivalents for repair and
replacement.

Emission Control System
Source of Emissions
The combustion process produces carbon monoxide, oxides
of nitrogen, and hydrocarbons. Control of hydrocarbons and
oxides of nitrogen is very important because, under certain
conditions, they react to form photochemical smog when
subjected to sunlight. Carbon monoxide does not react in the
same way, but it is toxic.
The U.S. and California Clean Air Act
EPA and California regulations require all manufacturers
furnish written instruction describing the operation and
maintenance of emission control systems.
to
The following instructions and procedures must be followed
in order to keep the emissions from your Honda engine
within the emission standards.
Tampering and Altering
Tampering with or altering the emission control system may
increase emissions beyond the legal limit. Among those acts
that constitute tampering are:
l
l
Removal or alteration of any part of the intake, fuel, or
exhaust systems.
Altering or defeating the governor linkage or
speed-adjusting mechanism to cause the engine to
operate outside its design parameters.
Problems that may Affect Emissions
If you are aware of any of the following symptoms, have your
engine inspected and repaired by your authorized Honda
servicing dealer.
l
Hard starting or stalling after starting.
Rough idle.
l
Misfiring or backfiring under load.
l
l
l
38
Afterburning (backfiring).
Black exhaust smoke or high fuel consumption.
MAINTENANCE
& ADJUSTMENTS
Proper Maintenance is the Owner’s
Responsibility
Replacement
Parts
The emission control systems on your new Honda engine
were designed, built, and certified to conform with EPA and
California emission regulations. We recommend the use of
genuine Honda parts whenever you have maintenance done.
These original design replacement parts are manufactured to
the same standards as the original parts, so you can be
confident of their performance. The use of replacement parts
that are not of the original design and quality may impair the
effectiveness of your emission control system.
Maintenance
Follow the Maintenance Schedule on page 41. Remember
that this schedule is based on the assumption that your
machine will be used for its designed purpose. Sustained
high-load or high-temperature operation, or use in unusually
wet or dusty conditions, will require more frequent service.

Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will
be too rich. Performance will decrease, and fuel consumption
will increase. A very rich mixture will also foul the spark plug
and cause hard starting.
High altitude performance can be improved by specific
modifications to the carburetor. If you always operate your
mower at altitudes above 1,800 meters (6,000 feet) have an
authorized Honda commercial mower dealer perform this
carburetor modification.
Even with the modification, engine horsepower will decrease
about 3.5% for each 300 meter (1000 foot) increase in
altitude. The effect of altitude on horsepower will be greater
than this if no carburetor modification is made.
pc?iq
When the carburetor has been modified for high altitude
operation, the air-fuel mixture will be too lean for low altitude
use. Operation at altitudes below 1,800 meters (6,000 feet)
with a modified carburetor may cause the engine to overheat
and result in serious engine damage. For use at low
altitudes, have an authorized servicing dealer return the
carburetor to original factory specifications.

Air Cleaner
Check that the air cleaner elements are clean and in good
condition. A dirty air cleaner will restrict air flow to the engine,
reducing performance. A damaged air cleaner will allow dirt
to enter the engine, causing rapid engine wear.
1. Remove the wing nut to
remove the air cleaner cover.
If the foam element appears
clean over more than half its
surface, it does not need
cleaning. Reinstall the cover.
If the foam element appears
dirty, go to Step 2.
2. Remove the other wing nut
and remove the elements.
3. Separate the foam element
from the paper element and
carefully check each one for
holes or tears. Replace any
damaged element.
4. Clean the foam element by
squeezing it in warm soapy
water, rinsing it, and allowing
it to dry. You may also use a
nonflammable solvent and
then allow it to dry.
Gasoline is highly flammable and explosive.
I
You can be burned or seriously injured.
Never use gasoline to clean engine parts. Use a
nonflammable solvent.
5. Oil the foam element by dipping it in clean engine oil and
squeezing out all excess oil. If too much oil is left in the foam,
the engine will smoke when you first start it.
42

MAINTENANCE & ADJUSTMENTS
6. Clean the paper element by tapping it on a hard surface to
knock off dirt or by blowing compressed air (at less than 207
kPa (30 psi}) through the filter from the inside. Never try to
brush off the dirt -that will just force it into the filter fibers.
7. Use a damp rag to wipe any dirt from the inside of the air
cleaner housing and cover. Be careful not to allow dirt into
the duct leading to the carburetor. Be sure the rubber seal in
the base is in place and in good condition.
8. Place the foam element over the paper element and install
them with the wing nut.
9. Install the cover with its wing nut.
INOTICEI
Operating the engine with no air cleaner or with damaged
elements can cause rapid engine wear.
Fuel
Fuel tank capacity:
16.7 liters, 4.4 gallons
Refueling
Remove the cap on the tank and check the fuel level. Refuel
carefully to avoid overfilling or spilling fuel. There should be
no fuel in the filler neck.
Gasoline is highly flammable and explosive.
You can be burned or seriously injured.
When refueling:
l Stop engine and keep heat, sparks, and flame away.
l Refuel only outdoors.
l Wipe up spills immediately.
Never refuel the mower inside a building where fumes may
reach an open flame or spark. Keep gasoline away from
appliance pilot lights, electric motors, etc.
Refuel in a well-ventilated area before starting the engine. If
the engine has been running, allow it to cool. Avoid overfilling
the tank or spilling fuel.
43
MAINTENANCE
&ADJUSTMENTS
-
Spilled fuel not only creates a fire hazard, it can cause
environmental damage. Wipe up spills immediately. Dispose
of gasoline properly.
Fuel Recommendation
Use unleaded gasoline with a pump octane rating of 86 or
higher.
This engine is certified to operate on unleaded gasoline.
Unleaded gasoline produces fewer engine and spark plug
deposits and extends exhaust system life.
Never use stale or contaminated gasoline or oil/gasoline
mixtures. Avoid getting dirt or water in the fuel tank.
Occasionally, you may hear light “spark knock” or “pinging”
(a metallic rapping noise) when operating under heavy loads.
This is no cause for concern.
If spark knock or pinging occurs at a steady engine speed,
under normal load, the engine can be damaged. Try using
fresh gasoline in the tank or change brands of gasoline. If
spark knock or pinging persists, contact your authorized
Honda Commercial Mower dealer.
Running the engine with persistent spark knock or pinging
can cause engine damage. This type of damage is not
covered by the Distributor’s Limited Warranty.
Oxygenated
Fuels
Some conventional gasolines are being blended with alcohol
or an ether compound. These gasolines are collectively
referred to as oxygenated fuels. To meet clean air standards,
some areas of the United States and Canada use
oxygenated fuels to help reduce emissions. If you use an
oxygenated fuel, be sure it is unleaded and meets the
minimum octane rating requirement.
Before using an oxygenated fuel, try to confirm the fuel’s
contents. Some states and provinces require this information
to be posted on the pump. The following are the EPA
approved percentages of oxygenates:
l
44
Ethanol (ethyl or grain alcohol) 10% by volume
MAINTENANCE
&ADJUSTMENTS
You may use gasoline containing up to 10% ethanol by
volume. Gasoline containing ethanol may be marketed under
the name “Gasohol”.
l
MTBE (methyl tertiary butyl ether ) 15% by volume
You may use gasoline containing up to 15% MTBE by
volume.
l
Methanol (methyl or wood alcohol) 5% by volume
You may use gasoline containing up to 5% methanol by
volume as long as it also contains cosolvents and corrosion
inhibitors to protect the fuel system. Gasoline containing
more than 5% methanol by volume may cause starting
and/or performance problems. It may also damage metal,
rubber, and plastic parts of your fuel system. If you notice
any undesirable operating symptoms, try another service
station or switch to another brand of gasoline.
Fuel system damage or performance problems resulting from
the use of an oxygenated fuel containing more than the
percentages of oxygenates mentioned above are not
covered under warranty.
Changing the Fuel Filter
Change the fuel filter at the recommended
interval.
1. Clamp off the fuel line between
the fuel tank and the filter to
prevent fuel flow. Use a small
locking pliers, hemostat, or other
device.
2. Place a container under the filter
to catch any spilled fuel.
3. Squeeze the hose clamps and
remove the lines from the filter.
4. Install the new filter with the arrow pointing toward the engine.
5. Be sure the clamps securely hold the fuel lines to the new
filter.
6. Dispose of the old filter and any spilled fuel properly and
remove the clamping device from the fuel line.
7. Check for leaks.

Before beginning the adjustment procedure, check the tires
for correct inflation and even wear. Worn or incorrectly
inflated tires can cause tracking problems. Check the
hydrostatic oil level. Operate the mower to bring the
hydrostatic oil up to operating temperature
At times during this adjustment procedure, you must run the
engine. Be sure there is adequate ventilation.
Direction Control Linkage Adjustment
Perform this adjustment if the mower creeps when the
direction control levers are locked in neutral with the neutral
locks.
1. Raise and support the rear of the mower so that the rear
wheels. are clear of the ground.
2. Lock the direction control levers in neutral with the neutral
locks.
3. Move the forward speed control levers full forward so that the
rollers do not contact the pump levers.
4. Adjust the direction control linkage on each side so that the
control arms on the side of each pump are vertical.
5. Hold an operator presence lever down on the hand grip for
the length of this procedure.
6. Start the engine and move the throttle lever to FAST.
7. Loosen the locknuts and adjust the direction control linkage
on each side so that the wheels do not rotate. Lengthening
the rod causes forward wheel rotation; shortening the rod
causes rearward wheel rotation.

Maintain the original angle
of the blade (about 30’).
Leave a blunt edge of 1
mm (‘4s - l/32 in). Do not
sharpen to a knife edge.
Remove an equal amount
of material from each end
of the blade to maintain
balance.
Do not remove material
from the inner area of the
cutting edge. If you need
to remove material to
restore the cutting edge,
taper the edge toward the
tip. Do not taper beyond
l/s of the blade width.
Do not grind the back side
of the blade.
Check the balance of the
blade by placing a dowel
through the mounting
hole. The blade should
